TOUCH PANEL AND DISPLAY DEVICE

摘要

A touch panel and a display device are disclosed. Either a cell or a cell, which is formed by the intersections of silver fine wires which form either first electrodes or second electrodes, forms parallelogram shapes (preferably rhomboids), having opposite angles wherein intersection angles are obtuse angles and intersection angles are acute angles. The first electrodes and/or the second electrodes have an adhesive (OCA) deployed thereupon, which has a loss coefficient (tan δ) of 0.13 or more at 140° C. and 1 Hz, and a reserve elasticity of 8.9×104 Pa or less at 25° C. and 1 Hz.

1. A touch panel having a first electrode layer and a second electrode layer, which face each other with an insulating layer interposed therebetween, wherein:
the first electrode layer includes a plurality of first electrodes extending along a first direction and arrayed parallel to each other along a second direction that is perpendicular to the first direction; the second electrode layer includes a plurality of second electrodes extending along the second direction and arrayed parallel to each other along the first direction; at least one of the first electrodes and the second electrodes comprises a mesh of fine silver lines each having a widthwise dimension of 4 μm or less; the mesh includes a plurality of cells defined by the fine silver lines crossing each other; at least one of the cells is of a parallelogrammatic shape having opposite angles for which crossing angles formed by the fine silver lines crossing each other are obtuse angles, and opposite angles for which crossing angles formed by the fine silver lines crossing each other are acute angles; and an adhesive, whose loss coefficient tan δ at 140° C. and 1 Hz is 0.13 or greater and whose storage elastic modulus at 25° C. and 1 Hz is 8.9×104 Pa or less, is disposed on at least one of the first electrodes and the second electrodes, which comprises the mesh and the insulating layer.
